REDIS: ⁣

service.health.v3.HealthCheckRequest

[service.health.v3.HealthCheckRequest proto]

端点健康状况: (repeated service.health.v3.EndpointHealth)

service.health.v3.ClusterEndpointsHealth

[service.health.v3.ClusterEndpointsHealth proto]

集群中端点的健康状况。集群名称和位置应与 ClusterHealthCheck 消息中的相应字段匹配。

{
  "cluster_name": ...,
  "locality_endpoints_health": []
}

集群名称: (string)

位置端点健康状况: (repeated service.health.v3.LocalityEndpointsHealth)

service.health.v3.EndpointHealthResponse

[service.health.v3.EndpointHealthResponse proto]

{
  "endpoints_health": [],
  "cluster_endpoints_health": []
}

端点健康状况: (repeated service.health.v3.EndpointHealth) 已弃用 - 端点健康信息的扁平列表。

集群端点健康状况: (repeated service.health.v3.ClusterEndpointsHealth) 按集群组织端点健康信息。

service.health.v3.HealthCheckRequestOrEndpointHealthResponse

[service.health.v3.HealthCheckRequestOrEndpointHealthResponse proto]

{
  "health_check_request": {...},
  "endpoint_health_response": {...}
}

健康检查请求

(service.health.v3.HealthCheckRequest)

只有 health_check_request，endpoint_health_response 可以设置。

端点健康状况响应

(service.health.v3.EndpointHealthResponse)

只有 health_check_request，endpoint_health_response 可以设置。

service.health.v3.LocalityEndpoints

[service.health.v3.LocalityEndpoints proto]

}

位置: (config.core.v3.Locality)

端点: (repeated config.endpoint.v3.Endpoint)

service.health.v3.ClusterHealthCheck

[service.health.v3.ClusterHealthCheck proto]

集群名称和位置提供给 Envoy 用于其健康检查的端点，以支持 Envoy 实例（在 HDS 之外）的统计信息报告、日志记录和调试。为了最大程度地发挥作用，它应该与 EDS 提供的相同集群结构相匹配。

{
  "cluster_name": ...,
  "health_checks": [],
  "locality_endpoints": [],
  "transport_socket_matches": [],
  "upstream_bind_config": {...}
}

集群名称: (string)

健康检查: (repeated config.core.v3.HealthCheck)

位置端点: (repeated service.health.v3.LocalityEndpoints)

传输套接字匹配: (repeated config.cluster.v3.Cluster.TransportSocketMatch) 可选的映射，通过健康检查时连接上的 health_checks.transport_socket_match_criteria 过滤。有关更多详细信息，请参阅 config.cluster.v3.Cluster.transport_socket_matches。

上游绑定配置: (config.core.v3.BindConfig) 用于绑定新建立的上游连接的可选配置。如果地址和端口为空，则不会执行绑定。
